I would really love to see a mod in which you can get captured by some of the organization in the wasteland and forced to do whatever they tell you. Some ideas include:
Some sort of slave organisation, similar to the slave town mod.
The Omertas forcing you to be a prostitute in Gomoragh
The Legion , if your a male then they will force you to become a legionarre and if female,,, well its pretty easy to guess if you even played a little bit of New Vegas
The Great Khans, Fiends, Vipers & Jackals.
And that pretty much is the list. If someone could please create this mod id be grateful.
